Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Butter: Creamed with sugar to trap air and give the cake a tender, rich crumb.
Brown sugar: Adds sweetness and moisture, and its molasses notes deepen the flavour and colour.
Molasses (in the method): Adds dark colour, moisture and a robust, slightly bitter sweetness.
Soda: Reacts with the molasses's acidity to lighten the batter as it bakes.
Eggs: Bind the batter and add structure and richness as they set in the oven.
Flour: Forms the gluten and starch framework that gives the cake its structure.

The step that matters

Add the soda to the molasses. Baking soda needs an acid to react with and release gas for lift. Molasses supplies that acidity, so the soda should be mixed in promptly, before the batter sits, to keep the rise effective.

Swap the nuts
